Abstract: The invention relates to a polycrystalline silicon rod, comprising an outer layer made of polycrystalline silicon having a thickness of 0.01 to 20 mm. Said outer layer contains crystallites having an average size of more than 20 µm. The invention further relates to a method for producing polysilicon by introducing a reaction gas containing a component that contains silicon and containing hydrogen into a reactor, whereby polycrystalline silicon is precipitated in the form of rods, characterized in that a temperature of the rods in a second step of the precipitation is increased by at least 50°C relative to a first step, a concentration of the component containing silicon in the reaction gas being 5 mol% or less and a supply of the component containing silicon being 0.25 mol per 1 m2 of rod surface or less in the second step of the precipitation. The invention further relates to a method for producing polysilicon by introducing a reaction gas containing a component that contains silicon and containing hydrogen into a reactor, whereby polycrystalline silicon is precipitated in the form of rods, characterized in that, after the end of the precipitation, a contamination-free gas flows around the rod-shaped polycrystalline silicon and the rod-shaped polycrystalline silicon is covered with a bag made of plastic and removed from the reactor.

Title: Multi-junction waveguide circulator without internal transitions
Inventor: KROENING ADAM M
IPC: H01P1/39
Filed: 2002-11-07
Abstract: An improved multi-junction waveguide circulator that eliminates the transitions to dielectric transformers and air-filled waveguides between ferrite elements is described. The waveguide circulator in accordance with the invention can be implemented in variations from a minimum of two ferrite circulator elements held in close proximity to one another to any number of ferrite elements as required to achieve the desired isolation performance or to create a switch matrix with any combination of input and output ports. The waveguide circulator in accordance with the invention eliminates the transitions between adjacent ferrite elements and thus reduces losses, component size, and mass.

Abstract: It is desirable to produce a ferritic stainless steel with corrosion resistance comparable to that of ASTM Type 304 stainless steel but that is substantially nickel-free for reduced cost. The ferritic stainless steel is dual stabilized with a titanium concentration of 0,10 to 0.25 percent by weight and a niobium concentration of 0.20 to 0.30 percent by weight to provide protection from intergranular corrosion. The steel further includes a chromium concentration of 20 to 23 percent by weight, a copper concentration of 0.5 to 0.75 percent by weight, and a molybdenum concentration of 0.20 to 0.60 percent by weight to provide pitting resistance without sacrificing stress corrosion cracking resistance. Such a steel is particularly useful for commodity steel sheet commonly found in commercial kitchen applications, architectural components, and automotive applications, including but not limited to commercial and passenger vehicle exhaust and selective catalytic reduction components.

Title: Apparatus to create an oil sand slurry
Inventor: MARKS ANITA
IPC: C10G1/04
Filed: 2008-06-19
Abstract: An improved method and apparatus for preparing and oil sand slurry. Mined oil sand ore is deposited into a rotatable breaker tube. As the rotary breaker rotates, the ore is advanced and broken. Process fluid may be differentially distributed throughout the length of the rotary breaker, forming an oil sand slurry and assisting in the comminution and ablation of the ore. The comminuted oil sand and process fluid passes through perforations in the interior surface of the rotary breaker, and are collected in a hopper below, while oversized ore lumps are ejected out of the discharge end of the rotary breaker. The rotatable breaker tube is resistant to backflow at higher infeed rates.
